APPLICATION SUGGESTION(Cont.)

LINEAR INTEGRATED CIRCUIT

For Low Cost Application

In low cost applications where the mP is not present, the suggested circuit is shown in Fig 3.

The ST-BY and mute terminals are tied together and they are connected to the supply line via an external voltage

divider.

The device is switched-on/off from the supply line and the external capacitor C4 is intended to delay the ST-BY

and MUTE threshold exceeding, avoiding “Popping” problems.
